IPG Photonics and TRUMPF Reach Global Patent Settlement Following Back-to-Back UPC Infringement Rulings

IPG Photonics Corporation (NASDAQ: IPGP), the world’s leading manufacturer of fiber lasers, announced on May 5, 2026 that it has reached a global settlement with Germany’s TRUMPF Laser- und Systemtechnik SE, resolving and dismissing all patent litigation between the parties worldwide. The agreement follows two successive infringement rulings by the Unified Patent Court (UPC) in February and March 2026—early high-profile enforcement actions in the young court’s history that drew close attention from patent practitioners across Europe.

Two Back-to-Back UPC Rulings

On February 25, 2026, the UPC Local Division in Mannheim ruled that IPG’s adjustable mode beam (AMB) laser products infringed TRUMPF’s European Patent EP 2,951,625. The judgment covered AMB laser products sold in seven UPC contracting member states, including Germany, France, and Italy—collectively representing less than 1% of IPG’s total sales.

A second ruling followed on March 16, 2026, when the UPC Local Division in Düsseldorf found that certain designs and uses of IPG’s AMB lasers also infringed European Patent EP 2,624,031. This decision covered sales in Germany, France, and Italy.

IPG had announced its intention to appeal both decisions and indicated it was implementing contingency measures to support customers of the affected products. The company had also filed a counterclaim against TRUMPF in the Eastern District of Texas.

Terms of the Global Settlement

Under the May 5 settlement, both parties agreed to dismiss all patent litigation worldwide. IPG recorded a charge of $13.5 million in its first-quarter 2026 financial results attributable to the settlement. Pursuant to the agreement, IPG will make a lump-sum license payment and ongoing royalties for the two European patents on a worldwide basis. In return, TRUMPF withdrew the UPC judgments, and IPG dismissed its Texas complaint. All cross-border proceedings between the two companies have now been fully resolved.

Significance for UPC Jurisprudence

The UPC, which opened its doors in June 2023, allows a single judgment to take effect simultaneously across all UPC contracting states—currently 26 EU member states. Unlike the pre-UPC era, when patentees had to litigate country-by-country in Europe, the UPC creates the possibility of pan-European injunctions and damage awards from a single proceeding.

The IPG–TRUMPF dispute became one of the first commercially significant cases to demonstrate the enforcement leverage the UPC can generate. Although the affected products represented less than 1% of IPG’s total revenue, the company accepted a $13.5 million settlement charge rather than face the continued risk of pan-European injunctive relief. Analysts have noted that the settlement reflects how UPC judgments—even when confined to specific product lines—can create sufficient commercial pressure to drive global resolution of patent disputes.

AMB fiber lasers, which allow users to dynamically switch between beam modes for precision welding and cutting, represent a high-value segment of the industrial laser market in which both IPG and TRUMPF are primary competitors. Their patent disputes had unfolded across multiple jurisdictions in Europe and the United States since the early 2020s.

For European patent holders and licensees, the case stands as a concrete illustration that UPC enforcement actions—coordinated across multiple local divisions—can materially accelerate settlement negotiations even where the direct sales impact of a ruling appears limited.
